This invention relates tobrake shoes' and'is illustrated as embodied in an `arcuate[and substantially rigid shoe suitable for' use in an internal expanding automobile brake. An object of the invention is to provide in an inexpensive manner a very strong shoe in which there is a stitl'ening web separate from the outer cylindrical part or band of the shoe and in which they are connected by means serving to brace them against each other. In one desirable arrangement there is a part, preferably separate from the stiiening web, engaging at one edge the inner face of the outer cylindrical part and at its inner edge "f engaging the stitfening web between its edges,

thus forming a brace which gives :with 'the stitfening web and the outer band a Very strong trussed section of triangular form. This bracing part is supplemented on the other side ot' the stiifening web with an anglesectioned reinforcing member closely' fitting within the junction between the cylindrical Web.

Other features of t e invention relate to details of the mount-ing of the bracing part and to other novel and desirable constructions Which will be apparent from the following description of several illustrative embodiments shown in the accompanying drawing, in which:

Figure 1 is a View of the novel shoe in side elevation;

Figure 2 is a section through the shoe on the line 2 2 of Figure 1.

As disclosed in the figures of the drawing, my novel shoe preferably includes an outer .welded `or otherwise secured `to thek inner 'face ot' theouter part l0?. On `thewopposi'te side 'of :the sti'llf'enin'g member is arranged another bracing member i8 lila-ruig `flanges at its edges welded or otherwisev secured respectively to.

the stift'ening men/ther 14 aiultheiiuner face 'of part 10, tlweenftaral .part-ot' which bridges cylindrical part or band 10 which may be l provided with any suitable brake lining 12 and between the edges of which there is arranged a stilfening member 14 engaging at its outer edge the inner face of the part 10 preferably substantially in the center rand preferably welded directly to the inner face of said part. A cylindrical band and stil'ening member are preferably bracedon oneside of the stiffening member by a stamping 16 approximately L-fshaped in cross section,'one flange of which is Welded `or otherwise secured to one side of the stiffeningmember l111 and the other flange of which is preferably 'dia'g'onz'illy i' rom the member 14 to the part 1() to `form a trussor "inclined Ybrace which, with member lli and part l0, forms a Very strong shoe portion ol'ltriangu'lar section.

At the anchored end ofthe shoe, the stili'- ening` member '1l projectsas an anchoring varm z2() oll'set `within 'the curve 2") -of the shoe to clear th'eeud of `the friction face `of `the adjacent shoe and nmy'beformed with a lsuitable openinr 24 to'be. `pivotally mounted on an anchor of anydesired form. The still'ening web of the shoe may also be `formed with an opcning'to allow for the passage of a post carryiig a plate bridging across adjacent ends of `two of theshoesand positioning them llaterally and said Webmay also Vbe formed with an openil'ig 28 for theanchor of the shoe overlapping the anchored end of the shoe shown in the drawing.I` A more complete disclosure of a brake of this character showingthe use of openings 26 and 28 `Will be Jfound in application No. 88,201, filed February 15, 1926.

A very strong and rigid lbrake shoe is thus yer member `and anfarcuatestiening member with 'its outer edge `engaging :the 4:inner `face of -theouter member, together ywith two separate brace memberson opposite sides of the stiiening member and secured to the outer member and the stiffening member and bracing them with respect to each other.

2. A brake shoe having a c lindrical outer member and an arcuate sti enin member with its outer edge engaging the mner face of the outer member, together with two separate bracing members on opposite sides of the 1o stlienmg member and secured to the outer with its outer edge enga 'ng the inner face l of the outer member, an means for bracing member and to the stiening member and g bracing the with res 1ect to each other, one

of sai bracing mem rs being L-shaped in cross section.

3. A brake shoe having a c lindrical outer l member and an arcuate sti ening member with :its outer ed e engaging the inner face of the outer mem er, together with a diagonally extending bracing member 'secured to ,said aforementioned members by anges paralleling the same.

.Y 4. A brake shoe having a c lindrical out- I er member and an arcuate sti ening member said members with respect to each other comprising a diagonally extending brace interposed etween said aforementioned members, said brace being secured to said members by flanges paralleling the' same, together with a second reinforcing member for the aforesaid 5;"Avbrake shoe first-mentioned members, the same being L- shaped i-n section.

member and a stiiening member secured to :said first-mentioned member along its outer edge, together with an an 1esectioned bracingcmember secured to said first-mentioned ,members on either side of their point'of connection.
